GENERAL DESCRIPTON
AVX Corporation has supported the Automotive Industry requirments for
Multilayer Ceramic Capacitors consistently for more than 10 years. Products
have been developed and tested specifically for automotive applications and all
manufacturing facilities are QS9000 and VDA 6.4 approved.
As part of our sustained investment in capacity and state of the art technology,
we are now transitioning from the established Pd/Ag electrode system to a Base
Metal Electrode system (BME).
AVX is using AECQ200 as the qualification vehicle for this transition. A detailed
qualification package is available on request and contains results on a range of
part numbers including:
• X7R dielectric components containing BME electrode and copper
terminations with a Ni/Sn plated overcoat
• X7R dielectric components, BME electrode with epoxy finish for conductive
glue mounting
